VISE

To all whom it may concern:

Be it known that 1, DE LOYD K, COOK, a citizen of the United States. residing'at Maquoketa, in the county of Jackson and State of Iowa, have invented certain new and useful Improvements in Vises, of which the following is a specification. p

This invention relates to an improved vise and has as its primary object'to provide a device of this character wherein the working face of the vise will be open and unobstructed so that access may be easily had to the work held against the said face.

The invention has as a further object to provide a vise having a main jaw and coacting clamping jaws mounted atopposite sides of the plane of the main jaw and arranged to coact therewith so that the working face of the main jaw will be open and unobstructed between the clamping jaws. The invention has as a further object to provide an arrangement wherein the clamping jaws may be simultaneously adjusted laterally with respect to each other for either increasing or decreasing the space between the said jaws and wherein the said clamping jaws may also be slidably adjusted simultaneously laterally in either direction with respect to the main jaw.

And theinvention has as a still further ob-' the clamping jaws of such nature that the said jaws will be rigidly supported against rocking movement with respect to the main 3 Other and incidental objects will appear as the description proceeds and in thedrawings wherein I have illustrated the preferred embodiment of the invention and wherein similar reference characters designate corresponding parts throughout the several views: i

ranged to cooperate with the main jaw of the device, v e

F g. 4 is atop plan view particularlyillustratmg the arrangement of the overlapping lateral lugs carried by the clamping jaws of the yise,'andj v v Flg. 5 1s a detall perspective view showmg one of the clamping jaws detached.

In carrying out the invention, Iemploy a stock 10,1'ormed adjacent its forward extrem1ty with an upstanding post 11. Fitted face or anvil 15. Formed in the rear side of I the said jaw is asquared socket'and removably fitted in the said socket, is a nut 16. Fitting over the socket for retaining the nut therein, is a plate 17 secured to the jaw by screws or other suitable fastening devices, the plate being formed with an opening to register with the opening in the nut. j 1

Slidably mounted upon the rod 12'of the stock 10 are upstanding coacting clamping jaws 18, one of which is shown indetail in Fig. 5. These jaws are arranged at opposite sides of the stock 10 and, at their upper extremities, confront the anvil15 ofthe jaw 14. Preferably, the upper terminals of the jaws 18 are laterally enlarged to extend inwardly toward the jaw 15 and thus present I correspondingly increased bearing surfaces to the work. Formed on the inner sides of the said clamping jaws are coacting over.- lapping lateral lugs 19, the innermost of which confronts the upper extremity of the post 11. Formed'in the said lugs are regis tering slots 20. Extending'loosely through the jawv 14 to project through the opening in the plate 17 is a clamp screw 21 threaded through the nut 16. This screw, at its for- 'l and arranged to confront the outermost of the lugs 19. Connected to the adjacent 'end of the clamp screw is aicap 25 and slidable through this cap is a handle 26.

It is now to be observed that the post 11 and collar 24 will hold the clamping jaws 18 against rocking movement upon the pin 12 with the said jaws thus rigidly supported to cooperate with the main jaw 1%. By rotating the i clamp screw 21 the clamping jaws may, as will be well understood, be slidably adjusted with respect to the main jaw or vice-versa depending upon whether o ot themain jaw is held fixed, it being observed, in'this connection, that when the clamp screw isturned to adjust the clamping jaws away from the'main jaw, the shoulder23ofthe said screw will engage the post- 11 for shifting th e stock lOoutwardly upon the main jaw, while, when the clamp screw is turned to adjust the clamping jaws inwardly, the collar 21 will cooperate with j the lugs 19 of the said clamping ljaws for shifting the stock 10 inwardly upon the main jaw. (I v V Fitted through the lower-extremities of the clamping jaws 18 is a reversely threaded adjusting screw 27 extending transversely between. the said jaws and mounted upon one end of this adjusting screw isa thumb nut 28 keyed orotherwise connected to the screw. Consequently, by rotating the nut 28, the clampin jaws may besimultaneously adjusted relative to eachother tofeither increase or decrease the space therebetween and willalsobe correspondingly adjusted laterally with respectto the main jaw 14. In use, the work such as a barj as conventionally shown at 29, isplaced against the anvil 15 o'fthe main j aw 1 1 when the clainp screw. 21 is operated to shift the clamping jaws to engage the said bar. The clamping jaws 18 will thus hold the work against the mairijaw 1 1; with the anvil of the main jaw-open and, unobstructed between the clamping jaws so that. easy access maybe hadto the work at theanvil and; as will be readily understood in viewof the previous description, the clamping jaws may be adjusted with respect to each other to engage the bar either immediately over-fthe anyil or at' 'points'spaced laterally with respect to the an vil. a I i l V Attention isnow directed to the fact that since the slotted lugs 19 ofthe clamping jaws 18 slidably receive the clamp screw 21, these jawsmay, by being connected by the adjusting screw 27, be slidably adjusted as plis'hed without molesting the adjustmentjof the jaws with respect to each ot lier. According'ly, the clamping jaws and adjusting screw may bebodily shifted laterally with respect to the main jaw for ad ustmg the clamping jaws to engage at different points with the work, this adjustment being of adwantage when it is desired to have one of the clamping jaws hold the work immediately at the anvil 15 with the other clamp toeach,otherfthe elugs 19 will engagethe clamp'screw 21 for limiting the jaws in their movementaway from each otherand prevent displacement. of the j aws, from, the rod Band will, pe form a similar function when the clamping; jaws are slidably adjusted laterally as a unit upon the said 1'0d.- a v a:

"Itwilljjtherefoiflbel seen that I provide a parti cula'rly 1 simple andjetlicient" arrangem ent "orthe jpurpose' set forth; and a vise adapted to} rigidly hold the work while, at the same tini edtlle construction is such that the wor l; will bej'exposed so" that easy access may behadlthereto'at the anv il or" the vise.

Having thus described the invention, what isjclaimed asfnew is: a a
